“For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life,”
For he who sows to his flesh
The idea of “flesh” is the sin capacity. If we give rope to our sinful tendencies, then we will reap those tendencies. Pandering to the flesh produces “corruption.” What we do in the energy of the flesh is not subject to reward.
It is possible to serve God in the flesh, but God will not reward this service.
Many Christians have the appearance of serving God, but all they are doing is operating in the flesh. Many people might announce what they do as spiritual, but God declares it as fleshly. It does not cut any ice with God at all. A person who deceives himself this way is in for a big surprise at the Judgment Seat of Christ.
